I don't know about other countries, but in the U.S., the IRS requires payers to submit a 1099 for total annual payments of $600 or more. Several companies have opted to send 1099's for amounts smaller than this. I received a 1099M from FT for a payout less than $600 (only joined in November of last year). I'm not sure how foreign based companies handle this (such as Canva and Alamy), but it is your responsibility to report any income from these and other companies, whether or not you receive any documentation from them.
